The Galaxy S10 represents the limits of smartphone design in 2019, but Samsung's plan is to eventually bury all of the sensors and cameras underneath the display, leaving nothing but a perfectly preserved screen.

Samsung said in a presentation last October that it was looking into several different technologies to maximize screen space, according to The Verge. "Hole display is not one of the design options, but it is a noteworthy achievement in terms of the display technological advances".

Ultimately when the technology does arrive in phones, it will likely be accompanied the integration of other technologies such as speakers and fingerprint readers in the screen itself, making the dream of the all-screen phone finally a reality. Yang admits that it won't be possible to build the true all-screen phone of the future for at least a few more years, but says it should be possible to hide the camera beneath the display within the next year or two.
